Figure 11 is a perspective View showing the stamped blank bent transversely at three points to provide the four sides of a section, the ends of the blank beingseparated.

Referring to the drawings in detail, it will be seen that the reference numeral 1 designates generally an assembled unit which comprises a plurality of distinct glass orpane supporting sections which are designated by the reference numeral 2 and illustrated to advantage in Figure 2 of the drawings. Each of the sections 2 comprises a polygonal frame which, as illustrated to advantage in Figures 8 to 11, inclusive, of the drawings, is preferably formed from a single strip of metal 3 which is adapted to be bent transversely at longitudinally spaced points to provide the upper, the lower and the vertical sides of the section frames. Substantially diamondshaped openings 4 are cut in the strip or blank 3 at the points therein where the same is to be bent and the ends of said strip or blank are also recessed or notched as at 5. One half of the strip or blank 3 is of materially greater width than the other half of said strip or blank to provide the longitudinal marginal extensions or flanges 6 which are incised as at 7 to permit transverse bending of-the comparatively wideportion of the strip or blank. The longitudinal center of the strip or blank 3 is crimped ina manner to provide aglass or pane engaging bead or rib 8 after which'the strip or blank is bent to the form illustrated to advantage in Figure 11 of the drawings and the ends thereof secured together by suitable means. It will thus be seen that a section has been provided having a vertical side and a lower side 9 and 10, respectively, whichare provided with the integral coupling flanges 6 and an upper side 11 and another vertical side 12 are provided which are not equipped with coupling flanges. All

of the sides of the section frames are provided with the inwardly extending glass or pane supporting beads or ribs 8, as will be readily v apparent.

l/Vhen the unit 1 isto be fabricated, the desired number of the sections 2 are assem- V bled with the sides 9 and lO of certain of the sections in abutting engagement with the sides 12 and 11 of the adjacent and the subjacent sections, respectively. In this position said sides 12 and 1 1 are disposed between the flanges 6 and said flanges are then bent or turned overthe marginal portions of the sides 12 and 11 in a manner to dispose their free marginal edges adjacent'opposite sides of the beads or ribs 8, as clearly seen in Figure 3 of the drawings; Thus theunflanged sidesll and 12 of thesections 2 constitute male membersand the flanged. sides 9 and 10 constitute female members. -In this manner the sections are securely connected together to provide a unit of the desired size or area such as is illustrated in Figure 1 of the drawings. i V i The interlocked sides of the sections con-- stitute mullions for receiving the window panes 13, said panes being secured in position by any suitable means such as putty or the like 14c. If desired, the frame sections may be constructed with the flanges 6 turned at right angles to their respective sides and the unflanged sides of the adjacent and the subjacent sections inserted therebetween or one of the flanges of each of the female sides may be turned to its final position and the corresponding marginal portion of the male flange inserted thereunder after which the other flange of the female side may be turned over the other marginal portion of the male slde, as suggested in Figure 6 of the drawings. Whenthe'latter method of assembly is resorted to the lastnamed flange extends in the plane of its respective side until the sections are position. relative to each other.

After the sections 2 are secured together in assembled relation in a mannerto provide the unitl anchoring bars orstrips are provided on the upper, lower and side edges of the unit. It will be seen that the female members or sides comprise one of the vertical edges and the lower edge of the unit 1 and the male members or sides constitutethe upper edge of the unit 1 and the other vertical edge of said unit 1. The anchoring bar or strip which is mounted on the side edges formed by the female members is designated by the reference numeral 15 and is folded or bent longitudinally upon itself to provide a flat bar of double thickness the longitudinal marginal portions of which are bent outwardly at right angles to provide the opposed, abutting anohoringflanges 16 to be anchored in the wall of a building in any desired manner. The flanges 6 are turned over the marginal portions of the anchoring bar 15 for rigidly securing said bar to the unit. The anchoring bars which are mounted on the side edges of the unit 1 which are formed by the male members or sides of the sections 2 are designated ed to provide an anchoring flange or lip 18 of'double thickness. the longitudinal marginal portions of the bars 17 being turned over the marginal portions of the male members or sides for securing the bars 17 thereon. It will be apparent. of course. that the anchoring bars on the side edges of the unit'l which are formed by'the female members or sides of the sections 2 maybe formed from a single. integral piece of'material and the anchoring bars17 on the other edges of the unit 1 may also be formed integrally with each other from a single piece of material. I It will be further understood that the 7 sides of the frames of the sections 2 may be formed of separate pieces of material which are secured together at their ends in any desired manner.

In Figure 4 of the drawings there is illusi trated a portion of aunit having mounted therein a swingable section which is designated generally by the reference numeral 19, said section being pivotally supported intermediateits vertical sides between the vertical mullions of t i unit as at 20.. In this form of the invention a male member 21 is secured inthe lower horizontally disposed female member 22 of the superposed section of the unit by turning the flanges of the female member 22 over the longitudinal marginal portio-nsof the male member 21. A longitudinal intermediate portion of the male member 21 is bent or folded in a manner to provide a longitudinally extending abutment 4:3. The vertical side members of the frame of the swingable sections 19 may be of any suitable construction to provide a tight joint with the adjacent vertical mullions of the unit when the swingable section is in closed position but the upper portion of the frame of the swing-able section 19 comprises a male member 24 of a cross sectional shape similar to the male sides or members 11 and 12 of the sections 2. A female member 25 is mounted on the male member 24 and comprises a metallic strip having one marginal portion turned over the corresponding marginal portion of the male member 24 as at 26. Intermediate portions of the female member 25 are then bent or folded in a manner to provide the spaced, parallel, longitudinally extending, upstanding abutments 27 and 28. -The abutment 27 is adapted for engagement with the abutment 23 on the male member 21 and the abutment 28 is engageable with the adjacent side of the female member 22 of the superposed sections of the unit. The female member 25 is then formed in a manner to provide a groove or channel 29 for the reception of the other marginal portion of the male member 24 and has its other marginal portion 30 disposed between the folds which form the abutment 27.

The arrangement at the lower end of the swingable section 19 is such that the identical elements which are used at the upper end are also used at the lower end with the only difference being in the arrangement of said elements. It will be noted that at the lower end of the swingable section 19 the male and female members 21 and 22 constitute the lower side of the frame of the swingable section 19 and the male and female members 24 and 25 constitute the upper portion or side of the subjacent sections of the unit. It will thus be seen that a construction is had which permits a swinging section to be provided in the unit and which requires a minimum number of different parts.

This arrangement provides two points of contact between the upper and lower sides of the frame of the swingable section 19 and with the lower side of the superposed sections of the unit and with the upper side of the subjacent sections of the unit. This provides a weather-proof joint, as will be apparent.

In Figure 5 of the drawings there is illustrated a slightly modified form of the invention illustrated in Figure 4. In this form of the invention there is provided a member 31 and a member 32 on the lower side of the superposed section of the unit, the member 32 being bent or folded longitudinally in a, manner to provide the spaced, parallel. longitudinally extending abutments 33 and 34. The abutment 33 is for engagement with the abutment 27 on the swingable section 19 of the unit. The abutment 28 of the member 25 is engageable with one side of the member 31 in the same manner in which the abutment 28 engages the member 22 in Figure 4 of the drawings. The abutment 34 is adapted for engagement with the side of the member 25 which is remote from the abutment 28 and in this manner a, three point contact is provided between the upper and lower ends of the secti-on 19 and the adjacent sides of the sections 2 of the unit 1. One marginal portion of the member 32 is: secured by the flange 35 of the member 31. The marginal portion of the member 31 which is remote from the flange 35 is folded upon itself as at 36 and the corresponding marginal portion of the member 32 is turned thereover. as at 37. As in Figure 4 of the drawings, the elements which are mounted on the ends. of the swingable section and the adjacent sides of the stationary sections of the unit 1 are reversed.
